[0001] This application is a division of application Ser. No. 10/389,828filed Mar. 17, 2003, which is a division of application Ser. No.09/776,434 filed Feb. 2, 2001, which is a continuation-in-part ofapplication Ser. No. 09/468,575 filed Dec. 21, 1999, now U.S. Pat. No.6,648,188.

[0002] The present invention is directed to a liquid containment anddispensing package, and to a method of manufacturing the same, in whichthe package container has a pour spout that is blow molded with thecontainer as a single unit.

BACKGROUND AND SUMMARY OF THE INVENTION

[0003] U.S. Pat. Nos. 4,917,269, 5,207,356 and 5,941,422 disclose liquidcontainment and dispensing packages in which the container has a pourspout that extends from the container dispensing opening to facilitatedispensing of the liquid content of the container into a dosagecap/closure. In containers for packages of this type, the pour spout istypically formed either separately from the container and secured as afitment, as in U.S. Pat. No. 5,941,422, or is formed integrally with thefinish of the container in an injection molding operation, as in U.S.Pat. Nos. 4,917,269 and 5,207,356. Forming a separate fitment forsecurement to the container finish in a post-molding operationundesirably increases the cost of manufacture. Likewise, use ofinjection molding apparatus to form the container finish and pour spout,followed by extrusion blow molding of the container body, undesirablyincreases the cost of manufacture by increasing the cost ofmanufacturing tooling. It has been proposed in the past to form thecontainer body, finish and pour spout in a single blow molding operation(followed by trimming as required), but the results have not beenentirely satisfactory.

[0004] It is a general object of the present invention, in accordancewith one aspect of the invention, to provide a container and closurepackage, and a method of making the same, in which the container body,finish and pour spout are integrally blow molded in a single operation,and in which the container finish has an internal throat of reduceddiameter adapted for sliding plug-sealing engagement with an inner skirtof the closure, while the outer skirt of the closure has an internalthread received over an external thread molded into the containerfinish. It is another object of the present invention, in accordancewith a second aspect of the invention, to provide a container fordispensing liquid product, a method of making such container, and acontainer and closure package, in which a pour lip is formed on thecontainer spout during the molding and/or trimming operation, forreducing drippage from the pour spout, and/or in which one or more dripledges extend around the external surface of the pour spout forcapturing any liquid that may drip from the edge of the pour spout andfeed such liquid back to the inside of the container. It is a furtherobject of the invention, in accordance with a third aspect of theinvention, to provide a closure for a container and closure package inwhich the closure is constructed for enhanced sealing engagement withthe container finish.

[0005] The present invention embodies several aspects, which may be usedseparately from or in combination with each other, and different aspectsof the invention have a number of alternative preferred embodiments. Acontainer and closure package in accordance with one aspect of theinvention includes a container having a body, a finish wall extendingfrom the body with at least one external thread, a circular throat at anaxial edge of the finish wall remote from the body and having a lesserinner diameter than the finish wall, and a pour spout extending axiallyfrom the throat at greater inner diameter than the throat. The containerbody, finish wall, throat and pour spout are of integrally blow moldedconstruction as formed, with the inside diameter of the throat beingoptionally reamed or otherwise trimmed as required for sealingengagement with the closure. The closure has a base wall, a peripheralouter skirt extending from the base wall with an internal thread forreceipt over the external thread on the container finish wall, and aninternal skirt extending from the base wall and spaced radially inwardlyfrom the outer skirt for sliding plug-sealing receipt within the throat,with the pour spout being disposed between the inner and outer skirts ofthe closure. The internal skirt may optionally have a circumferentiallycontinuous external bead for interference sliding fit within thecontainer throat to enhance sealing engagement between the internalskirt and the container throat. The pour spout has an angulated upperedge formed by trimming a moil from the spout in the container asmolded. A pour lip of increased inside diameter may extend part-wayaround the upper edge, and may be formed by molding a portion of thespout wall radially outwardly offset from the remainder of the spout andthen trimming the spout edge along a plane that intersects this offsetportion of the spout wall.

[0006] A container for dispensing liquid product in accordance withanother aspect of the invention includes a hollow body, a finish wallextending from the body with an external thread, a circular throat at anaxial edge of the finish wall remote from the body and having a lesserdiameter than the finish wall, and a cylindrical spout extending fromthe throat coaxially with the throat and the finish wall at a greaterinner diameter than the throat. The pour spout terminates in a planaredge at an angle to the axis of the spout to form a pour opening. Aplanar ledge externally extends around the spout at greater angle thanthe edge to the axis of the spout so as to be spaced from the edge atone side of the spout and to intersect the edge at an opposing side ofthe spout. The container body, finish wall, throat, pour spout and ledgeare of integrally blow molded construction as formed. Any liquid productthat may drip from the pour spout is captured by the planar ledge andfed by gravity back into the container body when the container body ismoved to an upright position. In the preferred embodiments, the bodyincludes an integrally formed handle, and the planar ledge is angled tointersect the edge of the pour spout adjacent to the handle.

[0007] A closure for a container and closure package in accordance witha further aspect of the present invention includes a base wall having aperipheral outer skirt with an internal thread for receipt over anexternal thread on a container finish. An inner cylindrical skirtextends from the base wall and is spaced radially inwardly from theouter skirt for sliding plug-sealing receipt within a throat on thecontainer. The inner skirt may have an outer surface with a radial stepthat is so positioned with respect to the thread on the outer skirt thatthe thread on the outer skirt engages a thread on the container finishbefore the step engages the finish throat. The internal skirt mayinclude a circumferentially continuous external bead for interferencefit within the container throat for improving the sealing engagementbetween the inner skirt and the container throat. This bead preferablylies in a plane perpendicular to the central axis of the closure, andpreferably is axially positioned to make sliding contact with thecontainer finish during the last half-turn of the closure onto thefinish.

[0008] In the preferred embodiments of the invention, a pour lip extendsaround an upper edge of the spout remote from the handle. The pour lipin various embodiments of the invention includes an undercut molded intoan outer surface of the spout immediately beneath the edge, ahook-shaped lip that extends radially outwardly from the spout at theedge, and a part-cylindrical wall portion radially outwardly offset fromthe pour spout. In several preferred embodiments, there are a pair ofparallel planar drip ledges externally extending around the spout andaxially spaced from each other for enhanced capture of any liquid thatmay drip from the pour lip.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0032] FIGS. 1-2 illustrate a container and closure package 10 inaccordance with one presently preferred embodiment of the invention ascomprising a container 12 and a closure 14. Container 12 includes a body15 having a closed bottom and a closed sidewall, and an axiallyextending finish wall 16 surrounding a dispensing opening. Finish wall16 is a cylindrical wall with one or more external threads 18 forsecuring closure 14 to container 12. A wall portion 20 angles radiallyinwardly and axially outwardly from the axially outer edge of finishwall 16 to a finish throat 22 of restricted diameter. The insidediameter of throat 22, which is preferably cylindrical, is less than theinside diameter of finish wall portion 16. From throat 22, the containerfinish extends axially and radially outwardly to form an elongatedcylindrical pour spout 24 that is concentric with throat 22 butdisplaced or offset radially outwardly therefrom. The upper edge ofspout 24 is trimmed along a plane 26 that is angulated with respect tothe central axis of the container finish. At the axial outer edge ofspout 26, a pour lip 28 is formed having an arcuate wall that is offsetfrom the cylindrical wall of spout 24. Pour lip 28 preferably extendsonly part-way around the circumference of spout 24, as best seen in FIG.2. Closure 14 includes a base wall 30, and integral outer and innerskirts 32, 34. Outer skirt 32 has one or more internal threads 36 forreceipt over external thread 18 on finish wall 16, and preferably has aslight outward conical flare. Inner skirt 34 is spaced radially inwardlyfrom outer skirt 32 concentrically with outer skirt 32, and has acylindrical outer wall surface 38. Base wall 30 is spaced from the upperedge of spout 24 and not in sealing engagement therewith.

[0033]FIG. 3 illustrates container 12 at an intermediate stage ofmanufacture. Container 12 is blow molded as a single unit, includingspout 24, throat 22, finish wall 16, external thread 18 and body 15.Container 12 is of generally uniform radial wall thickness as formed.Spout 24, throat 22 and finish wall 16 are concentric with each otheralong the central axis of the container dispensing opening. Spout 24 ismolded with a circumferentially limited wall portion 40 that is offsetradially outwardly from the main cylindrical wall of the spout. A moil42 and a flash pocket 44 extend from spout 24, as in conventional inblow molding containers, and must be removed in a post-mold trimmingoperation. Also in a post-molding operation, spout 24 is trimmed alongplane 26 (FIGS. 1 and 3) at an angle to the spout axis to form the upperedge of the spout, and to intersect offset spout wall portion 40 asshown. This intersection with part-cylindrical offset wall portion 40forms pour lip 28 (FIGS. 1 and 2). Container 12 may be extrusion blowmolded of any suitable material and trimmed as described employingotherwise conventional technology. See, for example, U.S. Pat. Nos.4,523,904 and 5,851,479. The inside diameter of throat 22 may also bereamed or otherwise machined to form an inner sealing surface that iscylindrical and coaxial with the container finish. Closure 14 may beinjection molded as illustrated, or compression molded in a suitableconventional manner.

[0034] Container 12 is filled by a packager, and closure 14 is thenfitted over the container finish. Inner skirt 34 engages the insidediameter of throat 22 in sliding plug-sealing facing engagement with theinside diameter of the throat. The inside diameter of throat 22 maybereamed as described above to enhance this plug-sealing arrangement.Outer skirt 32 is threaded over container finish wall 16. When aconsumer desires to dispense product from within container 12, closure14 is unthreaded from finish wall 16. The container contents are thenpoured from spout 24, either into the point of use, or into closure 14within inner skirt 34. Inner skirt 34 may include a mark 46 or othersuitable indicia for identifying a specific amount of product, such asone cup of detergent. The measured product may then be poured into thepoint of use, and the closure returned to the container. As closureskirt 34 is sealingly inserted through container throat, any excessproduct within the closure automatically drains into the container.

[0035]FIG. 4 illustrates a modification to the embodiment of FIGS. 1-3,in which the plane 26 at which container spout 24 is trimmed is at agreater angle to the axis of the container finish —i.e., 80° in FIG. 4as distinguished from 70° in FIGS. 1-3. The container of FIG. 4 isotherwise identical to that of FIGS. 1-3, and the closure in FIG. 4 isbasically the same as that of FIGS. 1-2.

[0036]FIG. 5 illustrates a modification to the embodiments of FIGS. 1-4,in which pour lip 28 is deleted. In the embodiment of FIG. 5 spout 24 issubstantially cylindrical throughout its entire length—i.e., having nopour lip 28 as in the embodiments of FIGS. 1-4. FIG. 6 illustrates thecontainer of FIG. 5 at the intermediate stage of manufacture at whichmoil 42 and flash pocket 44 are still attached. It will be noted in FIG.6 that spout 24 is substantially cylindrical throughout its length,having no offset wall portion 40 as in FIG. 3. Otherwise, the containerof FIGS. 5-6 is identical to that of FIGS. 1-3.

[0037] FIGS. 7-10 illustrate another embodiment 50 in accordance withthe invention. In this embodiment, the outer surface 38 of inner skirt34 includes an annular step 52 extending entirely around skirt 34 in aplane parallel to base wall 30. This step 52 is positioned axially ofskirt 34 such that step 52 and surface 38 are not brought into facingsealing engagement with the inside diameter of throat 22 until threads18, 36 become engaged. In this way, the user obtains the benefit of themechanical advantage afforded by threads 18,36 in sealing step 52against throat 22. Step 52 is preferably conical at an angle of about45°, as best seen in FIG. 10. The portion 54 of wall surface 38 insliding sealing engagement with the inside diameter of throat 22 ispreferably about one-half of the overall length 56 of throat 22. Whensurface 38 has an overall diameter of 1.884 inches, step 52 may have aradial dimension of 0.005 inch.

[0038]FIGS. 11 and 12 illustrate a container 60 in accordance withanother aspect of the present invention, including a container body 62with integral handle 64, externally threaded finish 66, circular throat68 and cylindrical pour spout 70. Spout 70 is trimmed along a planaredge 72 at an angle, preferably 70°, to the axis of the pour spout. Asmolded, there is a radial offset 74 (FIG. 12) in pour spout 70, and trimplane 72 is positioned to intersect the shoulder of offset 74 so as toform a sharp wedge-shaped pour lip 76 that extends part-way around thepour spout at the upper edge thereof remote from handle 64. As in priorembodiments, offset 74 extends only part-way around cylindrical pourspout 70. A planar ledge 78 externally extends around pour spout 70 atgreater angle to the axis of the pour spout than trim edge 72. Ledge 76is spaced from edge 72 beneath pour lip 76, and intersects edge 72 atthe rear edge of spout 70 (as best seen in FIG. 11) adjacent to handle64. Pour lip 76 helps prevent drippage of liquid along the externalsurface of spout 70 when pouring is arrested by return of container 60to the vertical orientation illustrated in FIG. 11. Any drippage thatmay occur past pour lip 76, which runs along the external surface ofspout 70, is captured by ledge 78 and fed by gravity (assuming upwardorientation of the container) along ledge 78 to the back edge of spout70 adjacent to handle 64, where the liquid is returned through thecontainer finish to the container body. Drip ledge 78 is preferably atan angle of 80° to the container axis. The upper surface 77 of dripledge 78 is at a small angle, preferably on the order of 3°, withrespect to a plane perpendicular to the spout axis. This angle promotescapture of any liquid that may drip past pour lip 76. Ledge 78 is moldedinto the container spout by means of a recess in the blow mold intowhich the material of ledge 78 is pushed during the molding operation.There maybe a slight indent at the internal surface of spout 70 oppositeledge 78.

[0039]FIGS. 13, 14 and 22 illustrate a container 80 in accordance with amodified embodiment of the invention. Container 80 has a cylindricalspout 82 with a pair of axially offset parallel drip ledges 84, 86.Ledges 84, 86 are each identical to ledge 78 in FIGS. 11 and 12. Aradially offset wall portion 88 is integrally molded part-way aroundspout 82 at a position remote from the handle of the container body, andthe spout is trimmed along the plane 90 as in prior embodiments. Anundercut 92 is molded into the outer surface of offset 88, and trimplane 90 is positioned to intersect the upper edge of undercut 92, andthereby form a sharp pour lip part-way around the edge of spout 82remote from the container handle. Once again, any liquid that may drippast the pour lip will be captured by drip ledges 84, 86 and returned tothe container body. FIG. 22 illustrates a package 140 that includescontainer 80 and a modified closure 142. Closure 142 has a base wall 30and an external skirt 32 with internal thread for securement to thecontainer finish as previously described. An internal skirt 144 dependsfrom base wall 30 radially inwardly of outer skirt 132 for plug-sealingengagement with throat 68. To enhance such sealing engagement, anexternal bead 146 is provided on the radially outwardly facing surfaceof inner skirt 144 for sliding abutting engagement with the innersurface of throat 68. Bead 146 is so positioned on skirt 144 as tocontact throat 68 during the last half-turn of the container thread.Such interference fit enhances sealing engagement between the skirt andthe container throat. Such interference may be on the order of 0.01inches entirely around bead 146. Bead has a rounded outer surface, iscircumferentially continuous, and lies in a plane perpendicular to thecentral axis of the closure. A circumferentially continuous rib 148extends downwardly from a shoulder on outer skirt 32 for abutmentsealing engagement with an opposing shoulder on container finish 66 toprovide secondary or back-up sealing between the closure and thecontainer finish. It will be recognized that provision of bead 146and/or rib 148 is not limited to the container embodiment of FIGS. 13,14 and 22, but may be readily employed in conjunction with thecontainers in other embodiments of the invention.

[0040]FIGS. 15 and 16 illustrate a container 94, again having an offsetportion 96 molded into pour spout 98 so as to extend part-way around thepour spout. A hook-shaped pour lip 100 is molded into the outer surfaceof spout 98. Hook-shaped pour lip 100 has a convex upper surface 102that extends radially outwardly and then axially downwardly with respectto spout offset portion 96, and a concave lower surface 104 that meetssurface 102 in a sharp downwardly angled edge spaced radially outwardlyfrom offset spout portion 96. Trim plane 106 is positioned to intersectthe upper edge of convex surface portion 102—i.e., where surface portion102 intersects the cylindrical outer surface of offset 96—so as to formthe hook-shaped pour lip 100 as previously described. Pour lip 100 isformed on the container spout during the blow molding operation, andthere may be a slight indent on the inner surface of the spout radiallyinboard of the pour lip.

[0041]FIGS. 17 and 18 illustrate a container 110 in accordance withanother embodiment of the invention. The portion of container spout 112at which pour lip 114 is formed is not radially outwardly offset fromthe main portion of spout 112, as in prior embodiments. Hook-shaped pourlip 114 has an upper convex surface 116 and a lower concave surface 118that meet in a sharp downwardly oriented pour edge. Pour lip 114, alongwith drip ledges 84, 86, is molded into spout 112 during the blowmolding operation. During this blow molding operation, a moil 120 (FIGS.19 and 20) extends upwardly from spout 112, and is trimmed from thespout along the trim plane 122. Trim plane 122 is positioned tointersect the upper edge of pour lip 114 in the container as molded soas to intersect the upper edge of pour lip surface 116. Trim plane 122is at a preferred angle of 70° to the spout axis, as in the priorembodiments.

[0042]FIG. 21 illustrates a modification to the embodiment of FIGS.17-18, in which container 130 has a shallower hook-shaped pour lip 132at the upper edge of spout 134. The lower surface 136 of lip 132 isconcave, as in prior embodiments, but does not close past a planeperpendicular to the spout axis. In a preferred embodiment, lowersurface 136 is at an angle of 5° to such plane. Pour lip upper surface138 is convex, as in prior embodiments.
